Designed for noise and vibration testing, imc
WAVE when used in conjunction with
CRONOS-PL hardware provides a
reliable, easy to configure and operate standards based testing system.
Hardware setup and software configuration can be further simplified by
using TEDS sensor recognition combined with ISO standard tests. The
system can be expanded with analogue and field bus channels (e.g. CANbus),
enabling the number of applications to be extended far beyond that of
conventional noise and vibration analysers. |

Specifications |
|
Personal Analyser
The "Personal Analyser" enables the user to perform custom analysis.
Using a combination of Digital Signal Processing techniques (Online
FAMOS) and the powerful FAMOS analysis software, engineers can develop
their own test routines combining data from a wide range of sources.
Standard measurement procedures such as those stipulated by DIN 45657,
EN ISO 5349-1 and ISO 2631-1 can also be carried out. |

WAVE is part of a large range of Intelligent
Measurement Systems that are used extensively in the mechanical,
automotive and power generation industries for applications such as R&D,
Testing and Quality Assurance. All systems are networkable, highly
dynamic and have real time capability. Possible measurements include
temperature, pressure, acceleration, vibration, voltage, current,
bridge, ICP, encoder and digital. All data acquisition systems are
supplied with configuration, operating and display software. Software
packages are available for post measurement data viewing and processing.
COM packages are available for integration into projects such as test
rigs. |
